My invention relates to closure devices for containers. An object of the invention is to provide a device which may be readily manipulated by a sliding movement to cause the opening and closing of containers, and which when manipulated into open position will still remain attached to the container.

The closure device embodies an elongated endless band of suitable material such as metal and Bakelite and at one end portion thereof carries a disk of cork or other sealing material which when the device is moved into closed position seals the container opening employed as an outlet or filling opening. The device may be used in connection with various containers such as tubes employed for tooth paste and shaving cream, containers employed for face powder and other toilet and medicinal preparations, and receptacles or tanks of automobiles. For use with such containers or receptacles it is customary to provide caps having rotative engagement with a neck member of the container and which when turned in one direction into open position are entirely free from the container. When thus manipulated, the caps are frequently dropped, which not only causes inconvenience but the caps are sometimes irretrievably lost. All such inconveniences are obviated by the use of my invention.

The novel features which I believe to be characteristic of my invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and method of operation, together with additional objects and advantages thereof, will be best understood from the following description of a specific embodiment when read in connection with the accompanying drawing, in which,

Fig. 1 is a vertical sectional view of the device in open position,

Fig. 2 is a vertical sectional view of the device in closed position.

Fig. 3 is a side elevational view of the device.

Fig. 4 is a top plan View of the device.

Fig. 5 is a perspective view showing the band portion of the device.

Referring to the drawing, the numeral 6 designates a container which may be either in the form of a collapsible tube or may be any container suitable for having my invention applied thereto. The container has a neck member 8, the upper end of which is provided with an external bead Hi. This bead is adapted to slidably retain an elongated endless band I2 upon the neck member 8. The band l2 may be made of any suitable material such as metal or Bakelite fashioned into sheet-like form, the material preferably being of a resilient nature. The middle of the band is provided with stops for retaining it in one or the other of its two extreme positions according to whether it is desired to have the closure device in open or closed position. As shown in Figs. 4 and 5, the stops may be provided by contracting the band at its middle to form a compound endless curve,

At one end the band 12 at its upper edge is provided with a projection 14 which is bent outwardly and then upwardly so as to be offset to an extend corresponding substantialy with the bead ID. The upper end of the projection I4 resiliently carries a disk 16 which extends toward the other end of the band l2 for substantially half the length thereof. A disk l8 of cork or other sealing material is secured to the lower surface of the resiliently mounted disk IS. The free end portion of the disk I6 is provided on its lower surface with a rib 20 which prevents wear on the sealing disk 18 when the device is being slid between open and closed positions. It is apparent from Fig. 2 that when the device is in its closed or sealing position, the rib 213 will also act as a stop to retain the device in this position.

The operation and advantages of my invention will be readily understood in connection with the foregoing description and the accompanying drawing. The device on account of the resilient nature of the band may be readily snapped upon the neck of the container and will be retained thereon for sliding movement by the bead If) so that the device cannot be dropped and lost. Assuming that the device is in open position, as shown in Fig. 1, and it is desired to close the container, the band will be slid toward the left into the position shown in Fig. 2. During sliding movement of the band in either direction, the rib 20 will ride on top of the bead l0 and prevent wear on the sealing member 18. When the device reaches its closed position the rib 2!) will drop from the head In, and, due to the fact that the disk I6 is resiliently supported, the sealing member 18 will firmly close the opening in the neck 8 of the container. The rib 20 serves as a stop to prevent the device from accidentally or unintentionally sliding into open position. When the band I2 is made in the form of a compound curve, as shown in Figs, 4 and 5, the contraction at the middle portion of the band serves as a stop to prevent the band from sliding until a certain amount of force is exerted thereon.
